The Science of Hair Growth

How the scalp, follicles, hair cycle and GHK-Cu copper peptides connect to healthier-looking hair routines.

Hair growth is not only about the visible strand. Every strand begins at the scalp, inside a follicle, and moves through a natural growth cycle over time.

CopperTheory builds haircare around GHK-Cu copper peptide, listed in formulas as Copper Tripeptide-1, alongside scalp-focused ingredients like Acetyl Tetrapeptide-3, Trifolium Pratense Flower Extract, panthenol, niacinamide, arginine, sodium hyaluronate and allantoin.

How Hair Growth Works

Hair grows from follicles located in the scalp. The visible strand is only one part of the story. Under the surface, the follicle moves through active growth, transition and resting phases.

This is why hair routines take time. A scalp routine used for a few days cannot transform the full hair cycle. A better approach is consistency over time.

CopperTheory focuses on the full scalp-to-strand system: shampoo to cleanse, conditioner to support softness and serum to target the scalp step.

Hair growth depends on

Follicle activity
The hair growth cycle
Long-term consistency

Scalp Health: Where Hair Begins

The scalp is the environment surrounding the follicle. If the scalp is neglected, the routine is incomplete.

A strong hair routine should not only make the strand feel smooth. It should also care about the scalp environment where healthy-looking hair begins.

Clean scalp

Shampoo helps remove build-up and prepares the scalp for the rest of the routine.

Comfort

Ingredients like panthenol, allantoin and sodium hyaluronate support a comfortable routine feel.

Consistency

Scalp routines should be simple enough to repeat over time.

Hair Follicles: The Starting Point of Every Strand

Every visible strand grows from a follicle. The follicle is an active structure embedded in the scalp and connected to the natural hair cycle.

Because follicles sit below the visible strand, serious haircare should think beyond shine and softness. The scalp and follicle environment are key parts of the routine.

Follicle-focused concepts

  • Hair starts below the visible strand
  • Follicles move through growth phases
  • The scalp environment supports the routine
  • Hair routines need patience and consistency
04

The Hair Growth Cycle

Hair moves through a cycle. The most common way to explain this cycle is through three phases: anagen, catagen and telogen.

Anagen

The active growth phase where the hair strand continues to grow from the follicle.

Catagen

The transition phase where the follicle begins shifting out of active growth.

Telogen

The resting phase before shedding and the next cycle begins.
